Jack, I erred in following the the logic the local G&F department uses. They say if the main powder charge and bullet go down the barrel from the front, it is a muzzleloader. I am aware/familiar of the slug guns with false muzzles; had some through a friends hands about a month ago. There used to be articles about them in the Gun Digest about 50 years ago (I'm an old fart). But if they are capable of being loaded from the rear, they call them a breach loader,ie, the Sharps paper cartridge rifles. If the "ball" can't be loaded from the rear, they are a muzzleloader. I will stand by that position; until someone shows me how I am screwed up!
